Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to an oxygen generator with silent air intake and exhaust. Background Technology

[0002] In the design of modern oxygen concentrators, noise reduction and space utilization efficiency are two key technical challenges. Traditional oxygen concentrators generate significant noise during operation, which not only affects the user experience but can also disturb the surrounding environment. Noise issues are particularly critical in scenarios requiring prolonged use, such as hospitals and home care facilities.

[0003] Current oxygen concentrators typically separate the intake and exhaust noise reduction modules. This layout not only occupies a large amount of space but may also result in poor noise reduction. The intake and exhaust pipes are often short, which fails to effectively reduce gas flow noise and also increases the size and weight of the equipment, reducing space utilization efficiency.

[0004] Furthermore, traditional oxygen concentrators lack integration and compactness in their structural design. Components such as molecular sieves, compressors, and gas storage tanks are typically installed separately, resulting in a loose overall layout and difficulty in achieving efficient space utilization. This design not only increases the equipment's footprint but also complicates installation and maintenance. Utility Model Content

Its advantages are that: the gas storage tank is located in the fourth space, the pressure equalization valve is located in the fifth space, and the pressure equalization valve is connected to the gas storage tank and the molecular sieve via pipelines, which improves the compactness and rationality of the oxygen generator structure, and this design improves the stability and safety of oxygen output.

[0017] As a more preferred embodiment, the aforementioned air-intake and exhaust-silencing oxygen generator further includes: an air inlet, which is horizontally integrated into the air storage tank, and the outlet end of the air inlet is connected to the air inlet of the air intake silencer module via a pipe horizontally penetrating the compressor cavity.
